Brake system
Electronic brake force distribution
system – EBD
The Electronic Brakeforce Distribution sys-
tem (EBD) is an integrated part of the ABS
system. The EBD system controls the brake
force to the rear wheels so that the best pos-
sible braking force is always available. Pulses
will be heard and felt through the brake pedal
when the system regulates brake force.
WARNING
If the BRAKE and ABS warning symbols are
lit at the same time, a fault may have oc-
curred in the brake system. If the level in the
brake fluid reservoir is normal, drive careful-
ly to the nearest authorised Volvo workshop
to have the brake system checked.
If the brake fluid is under the MIN level in
the brake fluid reservoir, do not drive further
06
before topping up the brake fluid.
The reason for the loss of brake fluid must
be investigated.

Emergency brake assistance – EBA
(Emergency brake assistance) In case of
sudden braking, full-strength braking is pro-
vided instantaneously. The EBA function
senses when heavy braking is underway by
registering how quickly the brake pedal is de-
pressed. Continue braking without easing off
on the brake pedal. The function is suspend-
ed when the pressure on the brake pedal
eases. This function is always active and
cannot be disengaged.
NOTE
When EBA is activated the brake pedal low-
ers slightly more than usual, depress (hold)
the brake pedal as long as necessary. If the
brake pedal is released then all braking
ceases.
